基於swarm的elasticsearch集羣搭建

es集羣構建：

1、安裝head插件：

  for Elasticsearch 5.x: docker run -p 9100:9100 mobz/elasticsearch-head:5

  （ docker run -p 9100:9100 10.211.121.26/library/elasticsearch-head ）

   出現問題

      head主控頁面是可以顯示的，但是顯示連接失敗

      “集羣健康值: 未連接”

   解決方案

    修改elasticsearch.yml文件

    vim $ES_HOME$/config/elasticsearch.yml

    # 增加如下字段

    http.cors.enabled: true

    http.cors.allow-origin: "*"

  運行：docker run -d -p 9100:9100 --name eshead 10.211.121.26/library/elasticsearch-head:5

2、安裝中文分頁插件：

  use elasticsearch-plugin to install ( version > v5.5.1 ):

  ./bin/elasticsearch-plugin install https://github.com/medcl/elasticsearch-analysis-ik/releases/download/v5.5.1/elasticsearch-analysis-ik-5.5.1.zip

3、修改系統參數：sysctl -w vm.max_map_count=262144

4、啓動elasticsearch集羣：

  master:

      docker run -d  -p 9200:9200 -p 9300:9300 -v /data0/elasticsearch/data:/usr/share/elasticsearch/data  -v /data0/elasticsearch/logs:/usr/share/elasticsearch/logs  --name elasticsearch 10.211.121.26/library/elasticsearch:5.5.1_ik

      docker cp  elasticsearch.yml  elasticsearch:/usr/share/elasticsearch/config/elasticsearch.yml

  data：

    docker run -d  -p 9200:9200 -p 9300:9300 -v /data0/elasticsearch/data:/usr/share/elasticsearch/data  -v /data0/elasticsearch/logs:/usr/share/elasticsearch/logs  --name elasticsearch 10.211.121.26/library/elasticsearch:5.5.1_ik

    docker cp  elasticsearch.yml  elasticsearch:/usr/share/elasticsearch/config/elasticsearch.yml

5、啓動kibana

 docker run --name kibana -e ELASTICSEARCH_URL=http://10.39.10.224:9200 -p 5601:5601 -d kibana:5.5.1

#在主機上給指定的node 添加 elasticsearch 標籤，限制es節點運行在指定主機上。

#  docker node  update  --label-add app_role=elasticsearch  nodename

#

#在swarm  master節點運行： docker stack deploy -c es.yml  es001  ,docker將自動完成集羣創建操作。
